▎ 摘  要

NOVELTY - The material comprises a density of 2-20mg/cm3, and porosity of 95-99%. A graphene filling is 0.2-2wt%, which achieves effective absorption in the 10-18GHz frequency band. the density of the three-dimensional ordered porous graphene aerogel is 4.5-15.5mg/cm3, the porosity is 97-99%, and the graphene filling is 0.2-1.2wt%. USE - Three-dimensional ordered porous graphene absorbing material. ADVANTAGE - The three-dimensional ordered porous graphene wave-absorbing material has simple process, low cost, ultra-low density, adjustable hole structure, low filling amount, and can effectively absorb ultra-wide band. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the three-dimensional ordered porous graphene absorbing material.
